sides; or by a ring or the like which encir-e cles the tube and attachment, or by other means. The top has a bead-flange at its periphery which cooperates with said means to hold the attachment in position.

The invention is clearly set forth in the following description and drawings: but I reserve the right to make changes which do not go beyond the principle of the invention or exceed the scope of the appended claims.

(ln the drawings,

Figure 1 is a side view of an attachment according to my invention in combination with ,a collapsible tube;

Figure 2 is a view of what is shown in i F re 1, seen from the left; igure 3 shows a modification; Figures 4, 5 and 6 are, respectively, a top, a side and a sectional view, of another form of the invention;

Figures 7 and 8 illustrate in side view two additional modifications.

The same numerals identify the same parts throughout.

The numeral 1 on Figures 1 and 2 indicates a collapsible tube with a soft body and the usualcomparatively rigid conical top 2 bearing a discharge nipple 3. The outer edge or periphery of the top projects beyond the circumference of the flexible body of the tube, forming a flange or bead 4:. The attachment 5 which is put over the top may have the form of a cover with a discharge nozzle 6, to receive the neck 3.

To support this tube I may utilize a stand comprising va pair of legs 7 pivotally or otherwise movably attached to a base 8 and the upper ends 9 of these legsmay be widened somewhat and have transverse grooves 10 on their inner faces to receive the beadfiange and the cover 5. The lower sides of these grooves form shoulders which pass under the bead 4 so that the tube is heldupright. in the stand. T 0 get the tube in the stand, the legs 7 are separated so that the tube bearing the cover 5 can be placed between the legs 7 and then the legs 7 are moved toward the tube to make the ends 9 engage the edge of the cover and the flange 4. To hold the legs in this position the stand may have a retaining ring 11, with bearing sleeves 12 that slide on the legs and adapted to encircle the tube LThe legs 7 normally diverge in a downward direction, and the ring is of such size that when it is moved down, the legs are forced to grip the tube between them, and when it is moved up the legs are separated enough to release the tube. Other means for engaging and releasing the legs may of course be employed.

The nozzle 6 which fits over the nipple 3 forms an extension thereof. This neck mounts an arm 13 which carries a valve or the like 14: with a cork or rubber gasket 15. The arm 14 is pivoted atlb at the side of the neck and has a handle 17. When the handle 17 is pressed the valve let can be moved and the contents of the tube expelled throughthe nozzle 6. v

The cover 5 bearing the nozzle 6 and the valve closure 1% is thus fitted to the top of the tube and held in place by the parts 9 of the legs 7 Whenever the contents of the tube are Wanted, the handle 17 is depressed to lift the cap valve closure 14 and then the tube is squeezed to discharge some of the contents through the nozzle-'6. So long as'the legs are in gripping position the stand supporting the tube and the element or cover 5 cannot be taken off, but when the attachment is to be removed, the legs 7 mustfirst be released and swung apart far enough to enable the outer edge of the cover to clear the grooves 10 in I the upper ends 9 of the legs 7.

Figure 3 shows in slde elevatlon a similar cover 5a with a nozzle 6a having a pivoted valve closure 14a attached to an arm 13a, pivoted at 16a on lugs 18 at the sides of this concave on their inner' faces.

nozzle 6a, and with a handle so that the cap 14a can be raised. The arm 13a and the nozzle 6a have engaging lugs 19 and 20, respectively, to keep the valve closed. In this form, however, the cover 5a is provided with a depending rim 21 which is cut at several points; or instead of a rim a number of projections extending downward past the flange 4, may be used. These projections may have their lower ends turned outward and to hold the cover on, I resort to a stand comprising two curved gripping parts 22 on a pair of legs 23. This stand is of the same construction as that described in my application Serial No. 247,500, filed January 18, 1928. It is made of the parts 22 and the legs 23 which are in the form of frames, each frame comprising apair of opposite side portions, the upper ends being joined by the parts 22, and the legs 23 being pivoted together. When they are moved to separate the ends 22 the member 5a is released; and when moved in the opposite direction the parts 22 engage the rim 21and hold the cover in place. This form of attachment is fully. set forth in my copending application Serial No. 300,892, for closures for collapsible tubes and other receptacles, filed August 20, 1928, of which this'case is in part a continuation.

In Figures 4, 5 and 6, the attachment or cover 5?) has a central extension or neck 25 with an opening therethrough to be put upon and enclose the neck'3of the tube. To hold the cover on, a binding device or ring indicated at 26 is provided, this device comprising curved sections 27 which are pivoted to the attachment at 28, and shaped so as to be Thus when the retaining device is applied, the ring in question surrounds the outer edgeof the cover 5b and the lower edge of the ring encircles the tube but 'just below the flange 4. Hence the cover 5b cannot be pulled 0E because the ring 26 holds it fast. The opposite ends of the sectionso'f'the ring can be secured by a catch 29,

which engages a stop 30. With thisform the cover can be taken offand put on easily, and it is held fast by the catch 26, which is releasable to permit the ring to be loosened and the cover to be removed when necessary.

This form of attachment is disclosed in my copending application, Serial No. 247,999, for accessory devices for collapsible tubes, filed July 23, 1928, whereof this case is a continr'iation to that extent. v

' In Figure 7 I show another formof cover 50 with discharge nozzle 6a to befitted upon the top and outlet neck 3 of the tube. The

cover carries a valve 14a and operating arm 13a as before, but the edge 24: of the cover is extended downward and is bent or crimped overthe fiange' l of the top' 2. The cover thus is held on and an additional stand or retaining ring is not needed. This form is also d1s' closed in my copending application Serial No. 300,892, above-mentioned.

In Figure 8, the cover 5d is similar to the member 5?) in Figures 4:, 5 and 6, but the rim .31 has inside guides 32 to screw upon the flange 4. The guides or threads 32 may be interrupted or continuous and have any desired cross-sectional shape. The guides 32 are shown in Figure 8 of the drawings in the nature of screw threads. But they may be simply separated non-continuous guides arranged in spaced rotation around'the inside of the cap with a slight inclination to act as a screw thread usually acts.

The attachment or cover in all forms protests the top 2, and helps it. to maintain its shape so that only the tube 1 is deformed in use. The attachment also provides the nozzle enclosing the neck 3, to cover the threads on the neck and prevent lodgment of the contents and dust on the neck, thus preventing uncleanness; and serves further to mount a valve or closure for the tube 1, as desired. The attachment is secured largely through the instrumentality of the flange 4.

In Figures 1 to 6, inclusive, the parts which engage the rini of the attachment or cover may be made to fit tight enough to compress tained with the attachment of Figure 7. I claim 1.
